PKI 2330Print

This Digital Spread Spectrum Audio Kit is the only answer to tasks where highest levels of security are required for monitoring purposes. The digitally scrambled signal is nearly impossible to decode and furthermore it will be transmitted on special frequencies spreaded over a wide frequency band. An unwanted listening to this transmission therefore is totally impossible.
